Power plant operators face a range of challengesincluding increasing the efficiency and extending

the life of existing equipment, installing new capacityand planning for the introduction of demanding newenvironmental requirements. ABB has the experience,products and technology to support operators

in all these activities.

High voltage motorsin power generation

ABB has a complete range of high voltage induction and

synchronous motors and generators in all applications

in power generation plants including the largest fans and

feed water pumps. Based on long experience of working

with users ABB has accumulated extensive applications

technology which is incorporated into the design of the

products.

ABB motors meet the highest standards of effic iencyand reliability and have the structural integrity to maintain

high levels of performance Also they are designed to with-

stand conditions arising in generating plants such as load

rejections or short circuits. Special care is taken when

guaranteeing starting performance because it is important

that the motors keep running during a voltage dip and

are able to re-accelerate after a t rip.

ABB is determined to remain at the foref ront of technological

development of products and of design and manufacturing

methods. This technology is applied to new products and

to upgrades of existing installations.

ABB is a world-wide enterprise with an extensive network

of sales, service and manufacturing facilities. This provides

fast and effective communication with all users and facilitates

close, long term cooperation.

Power plants are designed to operate for up to 50 years

and ABB maintains its support throughout, assisting plant

builders from the design stage through to helping users

to maintain and improve performance over the yearsof operation thereafter.

A power plant is crawling with electric motors. High and low voltage

AC Induction motors, high voltage AC synchronous motors and sometimes

also DC motors. Often there is a mix of old and new motors and a multitude

of different makes which, in itself, causes many challenges.

Reliability of the equipment is more important than anything

else in the operation of a power plant. At the same time it is

well to remember that every kWh of parasitic consumption

saved becomes another kWh that can be sold. ABB is the

market-leading supplier of motors and drives, providing

both savings and reliability.

The main areas of use for large HV motors are: Pumps in the

steam cycle and cooling system, fans in the flue gas system,

fuel supply, environmental systems and various support

systems such as compressed air. Significant improvements

in the heat rate can be achieved with co-generation or

district heating which also requires motors.

Do you know how many years your old motors have left in them?

Do you have a plan for which motors should be replaced first?Do you know where the low hanging fruits on efficiency improvements are?

Do you know where a variable speed drive can improve your process dramatically?

Contact ABB let us look at it together!

In addition to supplying highly efficient and reliable motors ABB offers

a wide range of services to support existing users of ABB equipment.

Support for users

These services range from assisting in planning maintenance

operations through to undertaking complete equipment

upgrades.

Current conditions often require that the life of existing

equipment be extended well beyond planned dates and

to meet these needs ABB offers comprehensive Life

Extension Treatments.

Such operations must be planned well in advance and

to help prevent major problems caused by premature

failure ABB has introduced LEAP (Life Expectancy Analysis

Program). This is a systematic approach to maintenance

management and equipment replacement decisions based

upon careful monitoring of the condition of the machines

and the stresses induced in them.

The part icular strength of LEAP is its abi lity to track the

development of vulnerabilities over time. Therefore LEAP

can be directly integrated in a general maintenance

program.

For critical applications on-line condition monitoring

can be arranged.

Upgrading can be undertaken in one of ABBs approved

workshops.

ABBs world-wide network of sales and service centres,

manufacturing facilities and logistics ensure users of

a prompt supply of quality assured ABB spare parts.

The introduction of ABB variable speed drives using

frequency converters to control motor speeds can achieve

significant savings in the power generating industry where

there is widespread use of wasteful components such asthrottle valves and fluid couplings.

The new chal lenge to the power generating industry will

be carbon capture and storage and it is expected to dwarf

all others problems. This will require very powerful drives

to handle large volumes of flue gas and even larger, more

specialised drives for the compressors used to transport

CO2

and to produce oxygen for combustion. ABB has

already built synchronous motors of more than 50 MW

output for just such applications.

Modern technology

ABB has always played a leading role in research and development and has

undertaken the rapid implementation of new technology into its products.

Some recent developments are very relevant to the power generation industry.

In all probability the carbon-restricted economy of the future

will trigger other requirements which cannot be accurately

foreseen today. ABB is especially well equipped to cope with

these challenges. For example, where the superior efficiencyand control of permanent magnet motors can be significant

or where the use of ABBs extremely large Very High Voltage

compressor motors connected directly to a 60 kV grid may

be decisive.

Designers and operators of power generation plants can

be confident that ABB motors incorporate many years

of experience, are well suited to the application and

are based upon the most appropriate technology.
